109            MITgcm is now able to write and (to a lesser extent) read NetCDF files.
110            The framework (the "MNC" package) has been tested by numerous developers
111            on literally dozens of machines and, for the past month, has been a
112            working part of our standard verification suite.  We encourage MITgcm
113            users (especially new users) to try out the MNC package since the model
114            output is now much easier to read and understand.  For further NetCDF
